Hydrogen Fuel Cell Basics Very Efficient! Fuel cells convert hydrogen into electricity through an “electrochemical process” 2H2 + O2 -> 2H2O, + Electricity + Heat No Exhaust! Very Quiet!
Bipolar plate (cathode) Diffusion medium Diffusion medium Bipolar plate (anode) Fuel Cell Stack Typically, stack composed of 100s of cells Membrane electrode ass’y HydroGen3’s stack puts out 94,000 Watts of electrical power
Fuel Cell Power Plant vs. the “Internal Combustion Engine” Source: Scientific American Hydrogen-powered fuel cell engine: TWICE the efficiency with ZERO emissions
Fuel cell power module Hydrogen storage Traction system HydroGen3 Fuel Cell Car
Shell Hydrogen Station in Washington DC • Five Year GM–US DOE $88 Million Fuel Cell Vehicle and Infrastructure • Demonstration Program First retail station in the nation to offer both gasoline & hydrogen The Benning Road Station
Shell Hydrogen Station in Washington DC President Bush refuels HydroGen3 at Shell Hydrogen station in Washington, DC (May 25, 2005)
GM – Government Demo Programs US Mail delivery in Washington, DC area (2004-06) 497,122 pieces of US Mail delivered in the first 19 months of the Program EPA Demo Program (2005-06) • GM also has programs with the US Military, and has just concluded one with DC DOT
Where do we get the hydrogen? Carbon-based Oil CH4 + H20 CO + 3H2 CO + H2O CO2+ H2 R Natural Gas R Reforming Coal R Hydrogen Nuclear E Biomass Renewable R Hydro E Electrolysis Wind E 2H2O 2H2 + O2 Solar E
Hydrogen can help with….. Petroleum Dependence Trade Balance Hydrogen Local Air Quality Global Climate Change (CO2) PM, HC, CO NOx, SOx CO2, N2O, CH4
Commercialization Challenges(it does no good if we can’t sell in high volumes…) • Cost (of the fuel cell system) • Hydrogen storage (since that determines driving range) • “Infrastructure” (namely, where do I refuel?)
World’s first drivable hydrogen powered fuel cell / by-wire vehicle (2002)
So, you see, in addition to being COMPLETELY CLEAN and VERY EFFICIENT, Hydrogen & Fuel Cells can also lead to VERY EXCITING new vehicles !! • - 0 to 60 mph < 10 seconds • - 300 mile range • - 10,000 PSI compressed H2 • By-wire controls • electric all-wheel drive • - 11 inch “skateboard” GM “Sequel” (2005)
Key Drivers • - Energy Independence • - Energy Security & Diversity • - Reducing Air Pollution • - Reducing Global Warming Emissions • - Protecting Public Health • Creating Jobs • Cars with performance & features beating expectations • Industry-Government partnership can play a key role in facilitating the commercialization of hydrogen and fuel cell technology
